## Server code borrowed from coolspeed/century project
69+
70+
It's just a simple chatbot i'm building to help teach me how golang works. Actual server code borrowed from coolspeed/century project! Will add more on top of that.
71+
## Feature
72+
73+
* High throughput
74+
* High concurrency
75+
* (Automatic) High scalability, especially on many-core computers. (Think of 64-core computers, as much as 4-core ones.)
76+
77+
## Detailed Information
78+
79+
You can find an even simpler chat server on:
80+
81+
[https://gist.github.com/drewolson/3950226](https://gist.github.com/drewolson/3950226)
82+
83+
(In fact I started my scratch from that.)
84+
85+
## Build and Run
86+
87+
1) First, you need to install `golang`, of course:
88+
89+
Download it from [https://golang.org/dl/](https://golang.org/dl/), or install go via your package management tool:
90+
91+
For Ubuntu:
92+
93+
```
94+
sudo apt-get install golang
95+
```
96+
97+
For Mac OS X:
98+
99+
```
100+
brew install go
101+
```
102+
103+
2) Now, just build.
104+
105+
`cd` into the repo directory.
106+
107+
To build the server, execute:
108+
109+
```
110+
make build
111+
```
112+
113+
3) Run
114+
115+
3.1 Run the chat server:
116+
117+
```
118+
./bin/go-chatbot-lab
119+
```
120+
121+
3.2 Run the chat client:
122+
123+
`Client`: You can use `telnet` as the client:
124+
125+
```
126+
telnet localhost 6666
127+
```
128+
129+
type anything.
